Offshoots for Mac

From Digital Waters:

About Offshoots
Animates the wallpaper of your desktop with growing trees. The growth follows some easy-to-hack parameters. The offshoots lazily follow your mouse cursor or random points. Also available as a screensaver.

- I really like my desktop wallpaper. Can I make the trees grow over it? Yes: you can set Offshoots to use you current wallpaper as the background. Or you can choose your favorite solid color. Or a mix of the two. The default option is to make it randomly choose among one of its predefined colors.
- What if I want it as a screensaver? The release contains a screensaver version of it too. Double click on it to install it. Or you can test the "ScreenSaver mode" in the standalone application.
- My desktop is always hidden. What if I want the trees more visible? You can choose the level of the window from the preferences. You can even set it as an always on top window, setting a low value (zero) for alpha: the Offshoots window always ignores your mouse clicks so you can interact with the other apps' windows as usual.
